An efficient and convenient method for the synthesis of 2-aryl substituted tetrahydropyran, tetrahydrofuran, and oxepine derivatives via intramolecular palladium catalyzed cyclization is developed. The two exo-cyclic double bonds at adjacent carbon atoms in these ring systems could serve as potential dienes for cycloadditionreactions.
